Application filed July 28, 1917. Serial No. 183,254.

. To all whom it may concern:

Be it known that I, Joan H. Lnrrnu, a citizen of the United States,- residing at Mason City, in the oounty of Cerro Gordo and State of Iowa, have invented certain new and useful Improvements. in Electrical Priming-Va rizers; and I do hereby declare the 0 lowing to be a full, clear, and exact description of the invention, such as will enable others slliilleddin thei1 art to which its. oma can uset esame.

'l us invention relates to new and useful improvements in electrical priming vaporizers for hydro-carbon motors, such as are used in automobiles.

The primary object of the invention is to provide means whereby such motors may be quickly and easily started, especially in cold weather, when the fuel is heavy and less vol atile.

A further object of the invention is to conneot a hydro-carbon reservoir embodying electrical vaporizing means to the carburetor and to the intake manifold whereby when the electrical means is energized, a suflicient P23 wt to the mtake manifold to facilitate quick and ready starting of the motor.

With these and other objects in view as will appear as the description proceeds, the invention comprises the various novel features of construction, combination and arrangement of parts as will be fully described hereinafter and afterward specifically claimed.

Referring to the drawings,

- Figure 1 represents a side elevation of the electrical priming vaporizer connected to the intake manifold and carburetor of a motor and the electrical circuit thereof, and

Fig. 2represents a vertical sectional view through the vaporizer.

Similar characters of reference are used to denote corresponding parts throughout the accompanying drawings and the following description.

In order that the construction and operation of the invention may be readily comprehended, I have illustrated an approved embodiment thereof in the accompanying drawings and will now proceed to fullydescribe the same, in connection with said drawings, in which A indicates a hydrocarbon reservoir and comprises a glass or other transparent cylinder 1 closed at its upper end by a peripherally flanged top plate 2 of gas willbe generated and ad and at its lower end by a similar flanged bottom late 3, suitable kets 4 being intel-posed between the en s of the cylinder and plates to make leak proof joints.

5 indicates a vaporizin shell or chamber which has its upper end 'ckened and provided with a centrally threaded opening 6.

The lower end 7 of the shell is threaded centrally through the bottom plate 3 so that the circumferential flange 8 rests firmly on the bottom 1plate to form a leak proof joints The she I is provided adjacent the flange 8 with an opening 9 which establishes com-,

munication between the interior of the shell and the reservoir. The lower end 7 of the shell extends through a right angular bracket 10 and is secured thereto by a nut 11.

A plug 12 having a reduced upper end is threaded into the lower end of the shell and is provided centrally with a socket 13 for the reception of the lower end of a coil casing 14, said casing extending upwardly in the shell or vaporizing chamber and having its upper end 15 dome shaped. The coil casing may be held within the plug 12 on an ins ating disk 16 in any suitable manner, such as by soldering or friction.

The cylindrical portion of the coil casin is lined with suitable insulating material 1% which extends up to the dome shaped end 15. A resistance or heating coil 18 is mounted within the casing 14 and has its lower end attached to the head of the bolt 19 extending through the plug 12 and disk 16, wt nile the upper end of the coil is attached centrally to the dome end 15 in any suitable manner. 20

indicates an insulatin sleeve surrounding the bolt 19, and 21 insu ating washers which serve to insulate the bolt from the plug 12. The bolt is also provided with a lock nut 22 and a thumb nut 23. v

An outlet pipe 24 extends centrally through the cover plate 2 and has its lower end threaded through the opening 6 in the shell 5 and terminates in close proximity to the dome end 15 of the coil casing. The upper end of the outlet pipe is integral with a cross head 25 having a restricted outlet pas sage 2-6 in one end, said passage being provided at its juncture with the outlet pipe 24 with a valve seat 27. A valve stem 28 is threaded through the other end of the cross head and has its outer end connected to an actuating rod 29 which is intended to extend through the automobile dash, in this instance, and be provided with an indicator closed shoulder 80 'on the outlet handle to indicate when the valve is open or By screwing the outlet pipe 24 through the shell 5, the top and bottom plates 2 end 8 are securely clamped over the ends of the cylinder 1 by virtue of the In order to manually E1 the fuel reser' web: A, when desired a t cook 31 is threaded-th'ro h the top ,1; 2. The normel su ply 0 fuel for reservoir A is automatically fed by the suction force of the engine through'a stand pipe 32 which extends upwardly tom the bottom plate '3 and terminutes in a. plane substantially with the top of the vaporizing chamber said standpipe serving as an over fiow p1pe when the device is not in operation to maintain a redetermined fuel level in the reservoir. his stand pipe 32 communicates with a threaded nipple 33 projecting downwardly from the bottom plate, said nipplebeing connected to supply pipe 34 by a .union 35. The other end of the over flow pipe 34 is connected to thenipple 36 of the carburetor 37 by a union 38. 39 represents the engine intake manifold and is connected to the carbureter 37 in the usual and well known manner. An outlet pipe 40 has one end connected to the cross head 25 and its opposite end connected to the intake mnnifoldin any suitable manner found most desirable for the purpose intended. 41 represents a buttery orother suitable source of current ccmnected in circuit with one end of a switch 42,'the switch contact point 42 being connectcd by a wire 43 to the bolt 19. The other terminal 'of the battery 41 is connected by a wire 44 to and grounded on the carbureter 37. A dash lulnp 45 is connected to the switch contact 42' byn wire 46 and to and grounded on the intakc inanifold by a wire *7, and serves to indicate-by its illumination when the switch 42- is closed.

In the operation of the apparatus the gasolene throttle lever is first moved to a closed position on the steering wheel of the automobile, after which the switch 42 is closed whereupon current will flow from the buttery 41 through the switch, wire 43, bolt 19, coil 18, coil casing 14-, plug 12, end 7, plate 33, pipe 34, carburetor 37, and wire H hack to the battery, thus energizing and heating: the coil 18 suliicicntly to vaporize the fuel within the chamber 5. At the same time the switch 42 is closed the valve '28 is opened so at to permit the hydro-carbon vapor to be sucked through thfi outlet. pipe 24-, passage 26, and pipe 40 to the intake manifold under the suction force of the engine for nick and easy starting of the engine. By nrst closin the engine throttle valve and opening vu. ve 28, and then turning over the "nginc, a. suction force will be created in the .:--\'ico sufficient to :udon'mtically draw fuel from the carburetor bowl to the reservoir.

After the engine has been started, the valve 28 is closed and the switch 42 opened end the'engine operated in the usual manner.

The lamp. 45 ispreferably colored red-- so that when it is illuminated it will readily.
